    Abstract: A method of fabricating a polycrystalline CVD synthetic diamond wafer is disclosed. A first polycrystalline CVD synthetic diamond wafer is grown using a CVD process to a first thickness on a substrate. A second smaller wafer is cut from the polycrystalline CVD synthetic diamond wafer. The second smaller wafer is located on a carrier, and further polycrystalline CVD synthetic diamond material is grown on the second smaller wafer to a second thickness to give a polycrystalline CVD synthetic diamond material having a total thickness of the combined first and second thicknesses.

    Abstract: A method of manufacturing synthetic diamond material using a chemical vapour deposition process, and a diamond obtained by such a method are described. The method comprises providing a freestanding synthetic single crystal diamond substrate wafer having a dislocation density of at least 107 cm−2. The synthetic single crystal diamond substrate wafer is located over a substrate holder within a chemical vapour deposition reactor. Process gases are fed into the reactor, the process gases including a gas comprising carbon. Crack-free synthetic diamond material is grown on a surface of the single crystal diamond substrate wafer at a temperature of at least 900° C. to a thickness of at least 0.5 mm and with lateral dimensions of at least 4 mm by 4 mm.

    Abstract: An optical element comprising a window formed of synthetic diamond material and an optical surface pattern formed directly in a surface of the synthetic diamond material. The window of synthetic diamond material is in the form of a wedged diamond window with non-parallel major surfaces defining a wedge angle in a range (1) arcminute to 10° and the optical surface pattern is formed directly in one or both of the non-parallel major surfaces. There is also described a laser system comprising the optical element and a laser having a coherence length, wherein the coherence length of the laser is greater than twice a thickness of the wedged diamond window at its thickest point.
